Description
Sustainable communities discourse, literature and initiatives have essentially excluded poor marginalized communities at a time when sustainability efforts require more stakeholders and stakeholder involvement. The families in poor marginalized communities of color in the United States are struggling to meet basic needs (food, medicine, shelter, safety). Additionally, in these communities there is a disproportionate level of forced mobility to prisons, jails and detention centers. These communities are unsustainable. This dissertation is comprised of three articles. I present in the first article (published in Sustainability Journal) an argument for a definition of sustainability that includes recognition of the major, complex and persistent problems faced daily by poor marginalized communities of color (African American, Hispanic/Latino, Native American) including those connected to mass incarceration and high recidivism. I also propose a system-of-communities conceptual framework. In my second article, I explore sustainability assessment tools and find them to be inadequate for measuring the progress toward sustainability of poor marginalized communities with high incarceration and recidivism rates. In order to fill this gap, I developed the Building Sustainable Communities Framework and a Social Reintegration, Inclusion, Cohesion, Equity (Social R.I.C.E.) Transition Tool, a qualitative interview guide (a precursor to the development of a community sustainability assessment tool). In the third article, I test the utility of the Building Sustainable Communities Framework and Social R.I.C.E. Transition Tool through a community-based participatory action study: The Building Sustainable Communities-Repairing the Harm of Incarceration Pilot Project. Three types of participants were included, formerly incarcerated, family members of formerly incarcerated and community members. The Restorative Justice Circle process (based on a traditional practice of Native Americans and other indigenous peoples) was also introduced to the groups for the purpose of having discussions and sharing personal stories in a safe, nonthreatening, confidential and equitable space. During the study, data was gathered for reflexive thematic analysis from two participant groups, in-depth interviews, focus groups and short qualitative surveys. The findings reflect the community is in dire need of a path to stability and sustainability and needs the knowledge and tools to help them make collective community decisions about present and future sustainability issues.

Description
Urban community gardens hold the potential to serve as a form of multifunctional green infrastructure to advance urban sustainability goals through the array of ecosystem services they afford. While a substantial body of literature has been produced that is dedicated to the study of these services (e.g., providing fresh produce, promoting socialization, and enhancing urban biodiversity), less attention has been paid to the strategic planning of urban community gardens, particularly in an expansive urban setting, and in the context of the co-benefit of mitigating extreme heat. The research presented in this dissertation explores the potential of community gardens as a form of multifunctional green infrastructure and how these spaces can be planned in a manner that strives to be both systematic and transparent. It focuses on methods that can (1) be employed to identify vacant or open land plots for large metropolitan areas and (2) explores multicriteria decision analysis and (3) optimization approaches that assist in the selection of “green” spaces that serve as both provisioning (a source of fresh fruits and vegetables) and regulating (heat mitigation) services, among others. This exploration involves three individual studies on each of these themes, using the Phoenix metropolitan area as its analytical backdrop. The major lessons from this piece are: (1) remotely sensed data can be effectively paired with cadastral data to identify thousands of vacant parcels for potential greening at a metropolitan scale; (2) a stakeholder-weighted multicriteria decision analysis for community garden planning can serve as an effective decision support tool, but participants' conceptualization of garden spaces resulted in social criteria being prioritized over physical-environmental factors, potentially influencing the provisioning of co-benefits; and (3) optimized urban community garden networks hold the potential to synergistically distribute co-benefits across a large metropolitan area in a manner that systematically prioritizes high-need neighborhoods. The methods examined are useful for all metropolises with a preponderance of open or vacant land seeking to advance urban sustainability goals through green infrastructure.

Description
The food-energy-water (FEW) nexus refers to the interactions, trade-offs, and relationships between the three resources and their related governance sectors. Given the significant interdependencies, decisions made in one sector can affect the other two; thus, integrated governance can reduce unintended consequences and lead towards increased resource security and sustainability. Despite the known benefits, many governance decisions continue to be made in “silos,” where stakeholders do not coordinate across sectoral boundaries. Scholars have begun to identify barriers to the implementation of integrated FEW nexus governance, yet there is still minimal understanding of the reasons why these barriers exist and no theoretical framework for evaluating or assessing FEW nexus governance. Integrating the theory of collaborative governance with the concept of the FEW nexus provides an opportunity to better understand the barriers to and structures of FEW nexus governance and to propose solutions for increased collaborative FEW nexus governance in practice. To investigate this governance system, I examined the collaborative governance of the FEW nexus in the context of extreme urban water challenges in two urban case cities: Phoenix, Arizona, USA and Cape Town, South Africa. First, I performed a media analysis of the 2018 Cape Town water crisis to understand the impact of the water crisis on the FEW nexus resource system and the collaborative governance employed to respond to that crisis. Second, I conducted a systematic case study of FEW nexus governance in Phoenix, Arizona to understand barriers to collaborative governance implementation in the system and to identify opportunities to overcome these barriers. Finally, I presented a framework of indicators to assess the collaborative governance of the local FEW nexus. This dissertation will advance the sustainability literature by moving the concept of FEW nexus governance from theory and conceptualization towards operationalization and measurement.

Description
Globally, rivers are being heavily dammed and over-utilized to the point where water shortages are starting to occur. This problem is magnified in arid and semi-arid regions where climate change, growing populations, intensive agriculture and urbanization have created tremendous pressures on existing river systems. Regulatory incentives have been enacted in recent decades that have spurred river restoration programs in the United States. But what kind of governance does river restoration require that is different from allocative institutional set-ups? Are these recovery programs succeeding in restoring ecological health and resilience of the rivers? Do the programs contribute to social-ecological resilience of the river systems more broadly? This study aims to tackle these key questions for two Colorado River sub-basin recovery programs (one in the Upper Basin and one in the Lower Basin) through utilization of different frameworks and methodologies for each. Organizational resilience to institutional and biophysical disturbances varies, with the Upper Basin program being more resilient than the Lower Basin program. Ecological resilience as measured by beta diversity (for the Upper Basin) was a factor of the level of hydrological and technological interventions rather than an occurrence of the natural flow regime. This points to the fact that in a highly-dampened and managed system like the Colorado River, the dampened flow regime alone is not a significant factor in maintaining community diversity and ecological health. A broad-scale social-ecological analysis supports the finding that the natural feedback between social and ecological elements is broken and recovery efforts are more an attempt at resuscitating the river system to maintain a semblance of historic levels of fish populations and aquatic processes. Adaptive management pathways for the future need to address and build pathways to transformability into recovery planning to achieve resilience for the river system.

Description
The construction industry generates tremendous amounts of data every day. Data can inform practitioners to increase their project performance as well as the quality of the resulting built environment. The data gathered from each stage has unique characteristics, and processing them to the appropriate information is critical. However, it is often difficult to measure the impact of the research across project phases (i.e., planning, design, construction, operation and maintenance, and end-of-life). The goal of this dissertation is to present how industry data can be used to make an impact on construction practices and test a suite of methods to measure the impact of construction research across project phases. The dissertation provides examples of impactful research studies for each project phase to demonstrate the collection and utilization of data generated from each stage and to assess the potential tangible impact on construction industry practices. The completed studies presented both quantitative and qualitative analyses. The first study focuses on the planning phase and provides a practice to improve frond end planning (FEP) implementation by developing the project definition rating index (PDRI) maturity and accuracy total rating system (MATRS). The second study uses earned value management system (EVMS) information from the design and construction phases to support reliable project control and management. The dissertation then provides a third study, this time focusing on the operations phase and comparing the impact of project delivery methods using the international roughness index (IRI). Lastly, the end-of-life or decommissioning phase is tackled through a study that gauges the monetary impact of the circular economy concept applied to reuse construction and demolition (C&D) waste. This dissertation measures the impact of the research according to the knowledge mobilization (KMb) theory, which illustrates the value of the work to the public and to practitioners.

Description
Farmer-Managed Irrigation Systems (FMIS) are community managed and operated irrigation systems, celebrated for their successful governance of water resources for many decades and in several countries. Nevertheless, in the face of climatic, political, and social change, their future is uncertain. This dissertation utilizes household adaptive capacity, socio-ecological system (SES) robustness, and the Institutional Analysis and Development framework to structure a multi-scalar and multi-stressor analysis of changes experienced in Nepal’s FMIS. The dissertation documents irrigators’ perception of environmental change, impacts, and response; diagnoses the multiple disturbances impacting the robustness of the FMIS; and analyzes changes in the FMIS as an institution over time, in an effort to understand the major drivers of SES change. Fifteen FMIS from five districts of Nepal were selected for the study. Data were collected through field observations, household surveys, key informant interviews, and focus group discussions. The status of the existing rules was compared with the data collected three decades ago in the Nepal Irrigation Institutions and Systems database. This study finds that FMIS’s robustness is threatened by uncertain water supply, inefficient infrastructure, scarcity of farm labor, weakening collective action, and natural disasters. Farm households, whose actions are necessary to sustain the management of FMIS, perceive environmental change differently according to their ecological region and position along the irrigation canal, leading to different adaptation strategies. Despite livelihood diversification, irrigators rely primarily on irrigation infrastructure management to respond to the impacts of environmental change. Institutional analysis demonstrates the evolution of FMIS in terms of working rules in the face of multiple stressors. In this study, payoff, information, and position rules have exhibited the most substantive change. However, boundary, choice, aggregation, and scope rules are less likely to change. The findings of this work point to the need for geographically differentiated adaptation support policies, and a need for closer attention to the dynamics of labor, environmental change, and institutional persistence in agriculture and irrigation sectors. FMIS being an exemplary institutional arrangement for the study of a SES, the research findings benefit similar institutions globally facing challenges to the sustainable governance of common pool resources.

Description
As India expanded its grid infrastructure, decentralized renewable energy technologies, such as off-grid solar, also emerged in parallel as an electrification solution. This dissertation critically examines the role of off-grid solar in facilitating rural electrification efforts in India. Specifically, it applies the frameworks of the multi-level perspective, capabilities approach, and energy justice to achieve three objectives: (1) trace the evolution of off-grid solar in India; (2) understand the role of solar micro-grids in improving household capabilities and well-being; (1) examine whether and how community-scale solar micro-grids can operate as just means of electrification. This research relies on qualitative case-study methods. The historical research in Paper 1 is based on published policy documents and interviews with energy experts in India. It finds that landscape-regime-niche actor relations and politics were crucial in shaping off-grid solar transition outcomes. There is also a narrative component, as the key narratives of energy security, environmental degradation, climate change and energy for development converged to create spaces for state and non-state interactions that could nurture the development of off-grid solar. The community-level research in Papers 2 and 3 analyze a local energy initiative of community operated solar micro-grid using semi-structured interviews and participant observations from three villages in Maharashtra. Solar micro-grids play an important part in expanding people’s choices and opportunities. The benefits are not uniform across all people, however. Increases in energy-related capabilities vary by economic class and gender, and to some extent this means certain biases can get reinforced. In addition, the inability of solar micro-grids to keep up with the changing electrification landscape and daily practices means that the challenges of affordability, reliability and community engagement emerged as important concerns over-time. Empirically, this dissertation finds that off-grid energy initiatives must be carefully designed to be in alignment with local values and realities. Theoretically, it adds to debates on justice in energy transitions by showcasing the regime-led innovations, and temporality elements of energy justice local energy initiatives.

Description
The phase change process of freezing water is an important application in several fields such as ice making, food freezing technologies, pharmaceuticals etc. Due to the widespread usage of ice-related products, process improvements in this technology can potentially lead to substantial energy savings. After studying the freezing process of water, the supercooling phenomenon was found to occur which showed a negative effect. Therefore, ultrasound was proposed as a technique to reduce the supercooling effect and improve the heat transfer rate. An experimental study was conducted to analyze the energy expenditures in the freezing process with and without the application of ultrasound. After a set of preliminary experiments, an intermittent application of ultrasound at 10W & 3.5W power levels were found to be more effective than constant-power application, and were explored in further detail. The supercooling phenomenon was thoroughly studied through iterative experiments. It was also found that the application of ultrasound during the freezing process led to the formation of shard-like ice crystals. From the intermittent ultrasound experiments performed at 10W and 3.5W power levels, percentage energy enhancements relative to no ultrasound of 8.9% ± 12.4% and 11.9% ± 24.6% were observed, respectively.

Description
Despite widespread acknowledgement of the need for transformation towards sustainability, the majority of cities appear stuck in incremental change instead of far-reaching, radical change. While there are numerous obstacles to transformational change, one critical aspect is the process of selecting impactful sustainability programs. The unique and complex nature of sustainability suggests a different approach is needed to program selection than is normal. But, to what extent are cities adapting selection processes in response to sustainability and what effect does this have on sustainable urban transformation? Could there be a more effective process to select programs with greater transformational potential? This dissertation investigates these questions using case studies and action research to add to the general knowledge of urban sustainability program selection and to develop practical knowledge (solutions) for more effective sustainable urban transformation.
The dissertation consists of three studies. Study 1 uses a case study approach to investigate existing sustainability program selection processes in three cities: Avondale, USA; Almere, the Netherlands; and Freiburg, Germany. These cities all express commitment to sustainability but have varying degrees of sustainable development experience, accomplishment, and recognition. Study 2 develops a program selection framework for urban sustainable transformation drawing extensively from the literature on sustainability assessment and related fields, and on participatory input from municipal practitioners in Avondale and Almere. Study 3 assesses the usefulness of the framework in a dual pilot study. Participatory workshops were conducted in which the framework was applied to real-world situations: (i) with the city’s sustainability working group in Avondale; and (ii) with a local energy cooperative in Almere.
Overall, findings suggest cities are not significantly adapting program selection processes in response to the challenges of sustainability. Processes are often haphazard, opportunistic, driven elite actors, and weakly aligned with sustainability principles and goals, which results in selected programs being more incremental than transformational. The proposed framework appears effective at opening up the range of program options considered, stimulating constructive deliberation among participants, and promoting higher order learning. The framework has potential for nudging program selection towards transformational outcomes and more deeply embedding sustainability within institutional culture.

Description
Scenario planning originally garnered attention within the corporate sector as a tool to manage energy transitions, but it has gained traction within the field of sustainability. It is a process for exploring potential futures and thinking critically about complex decisions that involve high degrees of uncertainty. It is also effective in shifting mental models, engaging diverse stakeholders, and enhancing organizational learning, making it ideal for the complex problems that sustainability seeks to address. The resulting insights from scenario planning are typically used in strategic planning, which further aligns it with sustainability’s commitments to action-oriented solutions.
As a highly participative process, its success hinges on inclusive and just engagement of participants. This dissertation employed a multimethod approach to address the question, “What impacts do social dynamics have on participation in scenario planning for sustainability?” First, I conducted an ethical exploration of participation, looking to the systemic societal factors that might function as barriers to authentic participation. Next, I conducted an ethnographic study of a scenario planning workshop to identify ways in which social influence and authority impact participation in the process. Finally, I piloted a psychology study that explored the impact of explicit acknowledgement of status differential and the use of pre-event brainstorming on participation in a small group task that parallels scenario planning interactions.
In doing so, this dissertation presents a conceptual framework from which to understand the role of participation in scenario planning for sustainability and coins the term “strawman participation,” drawing attention to the role and function of social influence in participatory processes. If “token participation” arises from participants not being granted decision-making power, strawman participation develops from social/structural barriers, then “authentic participation” allows for both decision-making power and social capacity for participation. Though my findings suggest that scenario planning utilizes methods to equalize participation and engage diverse participants, factors such as status differentials and gender dynamics impact authentic participation. Results of the pilot study point to the utility of status concealment and individual-level brainstorming to bolster participation. Ultimately, this work contributes to a more nuanced understanding of participation in service of more robust, pluralistic sustainability decision making.
